A starless Pickering's Triange
As far as I know, I was the first who published starless nebula images back in 2007. At the time the feedback was less than positive.
The reason to publish such a unorthodox images was that the starless version is a part of my processing workflow and it can sometimes show more than the actual image.
I have used this technique ever since and published some starless images now and then.
Starless images are very powerful, when I want to dig out some really dim objects in a very dense starfield. It makes processing so much easier, I don't need to be careful not to blow up the stars.
Normally all the stars are placed back with a zero data lost after processing is done.
Starless images are also a great help to see the actual structure in the nebula since human brains has a tendency to form a quasi logical shapes out of the random cloud of dots, like stars are.

Part of Veil Nebula supernova remnant, the Pickering's Triangle.Colors are from the ionized elements, Hydrogen, Sulfur and Oxygen. S-II = Red, H-alpha = Green and O-III = Blue. This is one of the most detailed image of the Pickering's Triangle I have ever seen.A wide field photo of the Veil Nebula supernova remnant
The Pickering's Triangle can be see at one o'clock position.
My blog post about the wide field shot can be seen HERE.Technical details:
